XDA stuck at Align Screen!

Hi,
I have a problem with XDA - it is stuck at the align screen and keeps looping the cross over the screen forever.
I have reflashed rom a few time, I have disassambled the phone - cleaned the contacts, cleaned the screen, removed the schotch from the lcd 4 connectors. I even tried to glue a big piece of schotch to the screen pull the touchscreen of the lcd a bit...
nothing helps so far!!!
Do I need a new touchscreen? I really would like to fix this one, because it shouldn't be broken - it looks so nice and clean!?!!!!
Please help me!!

I found that pressure applied to the bottom left corner of the touchscreen behind the today screen button will cure touchscreen problems. When dissasembled it would be the area where the 4 leads branch off the touchscreen. I tested by slipping a doubled over piece of paper under that left corner (with the unit fully assembled). It put just enough pressure on that area that the touchscreen started working again! Try it, might work.

Thanks, but nope - stucking a paper under the casing didn't help.
I have managed to get pass align screen by deleting welcome file on PocketPC/windows/startup, but still the screen is faulty as the bottom and the top part of the screen doesn't respond to stylus!
What could this mean? Is there something wrong with the robon cable? Could reattaching the ribon cable help?!

Guess what! Just fixed the touchscreen - everybody said it's impossible - I don't know how I did it - just removed the ribon cable and soldered it back - it worked for me!!
Thanks all!!

XDA iis digitizer replacement and align screen solved
Ok to start with it is nearly impossible to solder the ribbon from a new digitizer on to a ppc lcd. I screwed up a screen trying to do that with a so called fine soldering iron but this is micro soldering, looks to be only possible by a machine. Dont glue it either as i've heard its bad too but if some one has had success then post and let us know. I just sticky taped it to the 4 metal connection lines. The ribbon is slightly see through and can easily line up.
Now when I had done this the screen align kept cycling. Yes even up to 20 times would not fix it but if you go back to the ribbon connection and make sure it is exactly on mark then you'll know the connection is ok. If the align screen responds to your taps well then it is just either the ppc getting used to the new digitizer or what I found was shuffling around the screws and making sure the insides of the ppc were snug and nothing pressing too hard on the lcd. The comment on placing a piece of cardboard was a good sujestion as when I screwed the whole thing together it suddenly aligned.
When the ppc finished installing, the alignment was a bit off by half a centimeter so i ran the align screen utility from settings again and it aligned! Now it works. Fingers crossed.

No response from a seemingly perfect touchscreen.
Hello guys it seems you guys have mastered correcting touch screen problems. If you would take a moment of time out of your day to help a dumb college kid. I have a SX66 and it has worked perfect and has remained to be a cool phone thanks to this site and the developers. I have retraced my steps a million times and here is what happened. I was surfin the web on my phone at school and the battery dropped off. I put the battery back on but the phone would not power up. 30 minutes later I tried my backup battery and bingo it powered on. But the touchscreen does not work at all. I took the phone apart and made sure connections were good and all was good. And as a last resort I reflashed my copy of wm6 to the phone. There is no cracks or blemishes on the screen. Any ideas will be greatly appreciated

[Q] LCD Flex Cable Connector Port Broken

Hello, I saw that someone else asked a similiar question before but they did not word the question correctly and got little help.
On my HTC EVO logic board, there's three tan "ports" (I don't know what they are actually called). One for the front camera, one for the LCD, and one for the front panel.
While walking home one day, my screen started showing a dark spot. The spot got bigger, and I decided to take apart my phone (something I'd done before a few times) and try to clean things up. I put everything back together, and the LCD would not come on. After numerous tries, I finally decided the LCD was damaged. As I went back in the phone, I saw that regardless of whether you flipped the black tab on top of the LCD tan 'port' back or forward, the cable was capable of being pulled out, e.g., it was not secure. At the time, I thought nothing of it, but now that my new LCD should be here, I'm worried.
Is my LCD not working because the 'port' is broken? If so, what can I do to repair it? (I heard it is very difficult). I'm worried, because I paid a lot to buy a new LCD and will be unable to send it back.

Also, my front panel cable never sits 'perfectly'..that is, I have to connect everything else first, and then try my best with the front panel. The tape does not stay down flat completely.

These sorts of connectors can be fixed,but there is quite a bit of skill involved. Upload a picture and I can tell you better how hard it is. What I can tell you is that you probably cant do it yourself. I base this on the fact that those who have the necesesary skils will instantly know its going to be a pain. In fact,its easy to screw it up ,and sometimes you do,even if you DO know what your doing. Since I dont want to take my phone apart,Ill need to see a picture of it before I can tell you anything more. One thing to keep in mind is that sometimes the ribbon cable CAN be pulled out anyway,and is making good contact and there is some other problem. If you have not installed the new LCD,install it and see if it all works. If so,your good to go. As a general rule,the connectors are delicate and its not a good idea to pull them out. In fact,dont disconnect them if you dont have to. They have a limited number of connect/disconects they can take and they are very easy to break.

Well, I don't really have a means of taking a quality photo except with my computer webcam but I'll try in a second. I can't really show you because there isn't much to see. The little black bar that flips up and down to 'lock' the port is ineffective; the cable can be pulled out regardless. I know I can't fix the port/connector by myself, so I'm hoping that's not the issue. You have given me a lot of hope though. The new LCD should be here by Wednesday at the latest, so I'll be able to test it then.
Does my front panel affect the LCD? Since I dropped my phone on the corner, even with a new panel it does not sit 'perfectly'. I don't think they're related though.

I dont think so. I bet your ok. Just dont keep playing with the connector. I know,Ive done it. I sit there messing with it,wondering,is it broken? Is it good? Then the little black peice comes off in your hand or the plastic breaks and "well its sure broken now!" Remember,that little latch does not so much hold the cable in place as hold the cable against the contacts,if its making contact,its good to go.

Hi, all. The new LCD I receieved did not work. There are very minor differences in the two; such as some type of blue gunk on the silver part of the LCD, the connector is more of a dark orange on the new one while the original is a yellow-orange, etc. Also, again, the connector does not 100% fit in the slot. It goes in, but a small corner sticks out a bit and you have to either hold it in or clip it in [which I can't, because the black clip is broken].
The only possibilities I can think of are
A] Because the little black thing is damaged, no LCD will work in it. Therefore I need a new phone.
B] The LCD does not work.
C] The LCD is the wrong size.
At this point I want to just give up and get a new phone, which is very heart-wrenching because I love my EVO and I doubt I can afford the only other phone I like, the Samsung Galaxy S II Epic Touch 4G.

Is anyone able to identify what connector is used on this phone for the LCD? I broke a pin on the connector while trying to repair a cracked screen. I would like to buy it and re-solder it on to fix the phone.
Can someone link the correct connector maybe from digikey.com?

Broken latch
I too have a problem with the connector... the plastic part that connects the ribbon cable to the main board has broken. There must be a place to buy these tiny plastic latches... does anyone know? Your assistance will be greatly appreciated!

Replace Battery Guide and Question,

I recently had to replace my battery in the m8. I managed to find a retailor online, ordered it, came with a install tool and double sided tape to replace the one used before for the speaker covers on top and bottom.
There is so little into on this online, I followed a YouTube video on replacing the digitizer of the phone to learn how to open the phone to replace the battery. I can say from experience its pretty easy, more intimating then anything after watching the video first. After applying heat to phone, I used a hair dryer. Of cource removing the screws that are found after removing the speaker covers that are removed after placing heat. The video I saw suggested guitar pics. I had none and have no idea where to find them. So I used some old credit cards, along with gift cards. The phone was pretty easy to remove from shell after heat. Where I screwed up, and its not mentioned in any videos I saw. THERE IS A SMALL RIBBON THAT SPLICES FROM ANOTHER LARGER RIBBON NEAR OR EXACT LOCATION OF AUDIO BUTTONS ON SIDE OF PHONE. I believe that when opening the phone from frame I may have ripped this ribbon by opening it with a credit card and ever so silently pushing the card upwards to remove the phone from the frame. After replacing the battery and replacing the phone in frame, on first boot my audio buttons don't work. I removed the phone from frame and that's when I noticed the small ribbon that wraps around the side of the phone easily ripple able when using anything along the side of the phone to remove the frame. It's not mentioned in any videos I watched on YouTube, so BEWARE. I'm hoping if anyone knows if this ribbon is replace able and maybe how it might be replaced?? Also if anyone can confirm this ribbon is used for audio connection to buttons?? After noticing the F.UP, I can see how each connector is used to hit the audio up and down but am still puzzled as to why it needs this ribbon I believe. Would think that the audio connection after receiving a hit on up or down would send whatever signal thru the phone onto a much larger ribbon to the motherboard which is on top of the battery. Yes its the same as a small ribbon connection, but I don't see the reason of needing this separate ribbon that appears is just for audio, spliced from a larger ribbon. So I'm hoping that someone can confirm that this is the intenal setup and yes this ribbon is for audio. So that I can maybe replace it, or at least stop me from trying to figure out other reasons of why. But I at least wanted to warn other people of this before they tried to replace the battery themselves. Also if you do replace it and after booting phone on either side it appears that you damaged the digitizer cause maybe one or two buttons don't work on keyboard. Its most likely cause the screws on the frame under speaker covers are to tight. I did that also and thought I broke the digitizer removing the battery. But after removing screw's and enter the booting up the phone with no screw's but in frame, all keyboard functions worked. I then screwed each screw in and applied pressure , then turned phone on to make sure it wasn't to much. Just don't tighting screws with phone booted on, believe you could get a static charge and screw up phone. Hope this guide and question helps anyone replacing battery. Mine failed after using custom ROMs on 5.1.1 , phone began to not stayed charged for more then a hour, also wouldn't even accept a charge. Tried all other fixes, calibrating battery and all. After replacing phone works fine accept for audio which is a pain in the A$$ cause can't manually boot to bootloader on boot by hand.

Screw mix - system use 80% of battery now

Hi,
First you can all say i screwed up and i am stupid.... i assume and i feel stupid, trust me !
I don't know anything about electronic or programming as you but i want to share and maybe find a solution with you for my problem.
3 days ago, I wanted to clean my lens because some dust were on it, so i put out the 2 screws around the lens... of course i did not see they were different...because i am stupid with it ! when i clean it i mixed the two screws so the big one went to deep behind the plastic and make a perforation on a component.
I join a picture to let you see a small hole in the blue part on the right of the camera lens !
Since, the battery is down in 3hours. Android tell me the system use around 80% of the battery and it is warm on the plastic around the lens.
The wifi never want to be put on and the bluetooth too (the MAC WIFI is now : 02:00:00:00:00:00)
The telephone and the 4G are working perfectly
I tried to put a small electric scotch on the hole but this don't change anything.
I just want to use this phone as a phone now, i don't care if the bluetooth, the wifi or the camera is working well or not at all....
Is it possible with the hidden menu to disconnect this component???
Do you have a solution which allowed me to continue using this phone which is perfect otherwise?
Sorry for my english....as you can see, i am not so good with it !
Thanks in advance for your advice...

Any idea of
What is the component i touch with the screw???
how i can use the hidden menu to disconnect wifi and bluetooth???
Thank u

I have a vs985 & yours is a d855, but I think the boards are similar enough to try and help.
It's not a component you hit - it's just tape. I opened up my phone and tested that spot on the board with a DMM and it looks like a ground plane underneath the tape you punctured. That in itself shouldn't be causing your problems, but if your screw went through the ground plane & into the board it may be shorting something out which could be causing your issues. If that's the case I don't know if your phone is salvageable.
1)Try removing the back cover and see if the issues go away. There is a possibility that when you re-assembled the phone something ended up out of place/off its contacts.
2)Also, I'd take a closer look and see how deep the screw went. Maybe take a fine tip tweezer and see if there is some of that ground plane mashed in the hole & try to gently peel it out.
3)And, of course, try resetting your phone or even re-flashing at some point - just so you can know for sure you didn't have some weird software glitch that just happened to show up after you opened your phone.
Hidden menu - I've never used it and I'm not on stock so I can't tell you much about it's functions. Here's a link... https://www.reddit.com/r/LGG3/comments/3z4nwi/lg_g3_hidden_menu_on_60_marshmallow/
Good luck - hope you get it sorted out

thanks,
I ll try tomorrow and tell you ASAP !!
THX again to spend time for me

Crack open M8 case and swap battery daily

Not really possible to do this if you wanna put the screws where they belong.
However I just noticed that the case can be removed pretty quick and pain free with just a thumbnail and a guitar pick as long a s you prop the top with the pick, and slide the strong thumbnail all along the non vol button side. I was surprised how easily the snaps popped and the side lifted up. After which it was easy to remove the glass and bulk innards of the m8.
...anyways, when I cracked one of my repair jobs open just now I found an entire ribbon from the motherboard not plugged in. The one on the upper left that come from under the motherboard and attaches at the sisterboard
Anyone know which this controls?
This phone was recieved as a "No power up, no charge" purchase.
Hoping for another quick fix here.
When that ribbon was partway plugged the vibrate bobin continuously went, then a satisfying end to oscillating bobin vibration when I got it in place.
So it clearly has plenty of battery. Yet still refused to turn on even after the 2 minute long press of power+vol up which is suggested throughout the world to solve no power up problems. Also tried the 20 sec power hold then short vol up push followed by 10-15 sec power + vol up hold. Nothing.
I had not plugged it at that time.
Both m8 I opened today were previously opened phones and both opened easily. Planning a usb port swap if I can't get this one to work.
Anyone got any other ideas on getting the battery working let me know.

Actually, to correct this, no guitar pick is needed at all now. I can pry all with my strong thumbnail. The thumbnail is only 1.5 mm. The top is the start point, get it up so it doesnt go back in, say 2mm from back case, then the non volume button side, then the vol side sliding both sides from top to bottom in turn, (you should be able to hear each snapping clip pop out, 4 per side, as you slide. Then the phone body will pop out of the case as easily as a samsung.

couple of videos
